UNITED STATES PATENT OEEIc ARTHUR RADIGUET, OF PARIS, FRANCE, ASSIGNOR TO HENRI DE TI-IIER- SANT AND HANS JACOB NORBALLE, OF LONDON, ENGLAND.

ELECTRIC GAS-LIGHTER.

SPECIFICATION forming part of Letters Patent No. 710,802, dated October 7, 1902.

Application filed February 28, 1902. Serial No. 96,139. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR RADIGUET, a citizen of the Republic of France, residing at 15 and 15 Boulevard des Filles du Oalvaire, Paris, France, have invented new and useful Improvements in Electric Gas-Lighters, of which the following is a specification.

This invention is an improvement in electric gas-lighters of the kind described in the specification of United States Letters Patent No. 658,290, dated September 18, 1900; and it consists in the novel features hereinafter described, reference being had to the accompanying drawings, which illustrate one form in which I have contemplated embodying my invention, and said invention is fully dis closed in the following description and claims.

In the accompanying drawings, Figure 1 is a side elevation of a gas-lighter having the improvements applied thereto. Fig. 1 is a View of a detail showing parts in a diiferent position. Fig. 2 is an elevation at right angles to Fig. 1. Fig. 2 is a view of a detail showing parts in a different position. Fig. 3 is an elevation of the device, showing the opposite side to that in Fig. 2. Fig. 4 is a diagrammatic view showing the electrical connection of the parts. Fig. 4 is a view of a detail.

Referring to the drawings, A represents the gas-supply pipe; B, the frame of the ignition device which is adapted to be attached to the pipe in any desired way. G represents the main burner, and D represents the by-pass or pilot burner.

E is the cock-plug, which is so formed that during a definite fraction of a revolution (in this instance onequarter) it will first cause gas to be admitted to the bypass or pilot burner D and by a further revolution cut olf the by-pass burner and admit gas to the main burner C. The next quarter of a revolution of the cock-plug will cut olf the supply of gas to the main burner, the next two quarter-revelntions repeating the cycle just outlined, as in the patent above referred to. i

Z) represents an electromagnet mounted on the frame B and provided with an armature f on an armature-lever which is pivoted at f. The cock-plug E is provided with a ratchetwheel g, secured thereto, and the armaturelever is provided with a pawl (or pawls) LI, which engages the ratchet-wheel and effects a partial rotation of the wheel and cock-plug until stopped, as hereinafter described. The pivotf of the armature lever has connected to it the vibrating contact 0 of the sparking device, which engages the fixed contact (1 at a point above the pilot or by-pass burner, thus serving to ignite the latter.

By reference to Fig. 4 the general arrangement of the electrical connections will be seen. In this diagrammatic view, a represents the battery, from which the main cir cuit is conducted by wire 1 to the electromagnet b, thence by wire 2 to the movable contact 0, thence through fixed contact d and wire 8, through a sparking-coil F, to a circuit-controlling device e, (in this instance an ordinary push-button with normally separated contacts,) and thence to battery a.

It represents a movable arm or lever pivoted to the pawl-lever i and provided with a projection or heel h. Anormally open shuntcircuit extends from wire 2 over wire 4 to said arm or lever h, to which it is electrically connected, and said arm or lever is provided with a contact 0, adapted when the lever is lifted to make contact with a spring-contact Z, connected by a wire 5 to the main circuit, (in this instance to the fixed contact d.)

The disk g is provided with a number of lugs orprojections 7;, adapted during the rotation of the disk to strike the nose or projection 7t and elevate the lever it, so as to bring the contact 0' into engagement with the spring-plate Z.

The operation of the device is as follows: The operator desiring to light the burner presses the push-button e and holds its contacts together. The armature f will be vibrated in the ordinary manner, thus vibrating the contact 0, so as to cause sparks to pass, and also turning the cock-plug E by means of the pawlt' and disk As the plug begins to turn gas will be admitted to the by pass burner D and will be ignited by the sparks, the further rotation of the cock-plug admitting gas to the main burner O, which is ignited by the pilot-burner, and then cutting olf the supply of gas to the by-pass burner and extinguishing it. In the present arrangement this will be accomplished by a quarter-rotation of the disk and cock-plug, when one of the pins 70 in the disk g will engage lever h and raise it, thus closing the shunt-circuit and short-circuiting the sparking contacts. The armature fwill thus be arrested and held to the magnet b, and no further rotation of the disk and no further operation of the sparking devices will be effected. The operator now removes-his finger from the button e and allows the circuit to break at this point. The armature f will be drawn away from its magnet b by the usual retracting-spring. To extinguish the light, the operator will close the circuit at the button e, when the cock-plug will be rotated a quarter-turn. The first movement of the ratchet-wheel will cause the nose 71' to drop off of the stop-pin It, and further rotation of the cock will cut oil": the supply of gas to the main burner, the rotation of the plug being arrested by another of the projections Z0 engaging and lifting lever h, as previously described, when the parts are in position to have the entire cycle of operation repeated during the next half-revolution of the cock-plug and disk.

The cock-plug is advantageously made with a handle or key 19 in the form of a pointer or index, so that the operator can ascertain the position of the cockthat is to say, whether it is open or closed-by the position of this pointer.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. An electric gas-lighting device comprising a burner, a cock-plug provided with a ratchet-wheel, for controlling said burner, a sparking device, a magnet, an armature for operating said sparking device, and ratchet- Wheel, a shunt-circuit connected with said magnet for cutting out said sparking device,

through said magnet and sparking device, a

circuit-controller for said main circuit, a shunt-circuit for cutting out said sparking device, and devices on said ratchet-Wheel for closing said shunt-circuit to stop the rotation of said ratchet-wheel and cock-plug, substantially as described.

3. An electric gas-lighting device, comprising a main burner, a by-pass burner, a cock controlling both burners, and provided with a ratchet-wheel, a magnet, a sparking device, an armature operatively connected with said sparking device and provided with a pawl for operating said ratchet-wheel,a shuntcircuit for cutting out said sparking device and stops on said ratchet-wheel for closing said shunt-circuit and stopping said ratchetwheel, substantially as described. I

4. An electric gas-lighting device comprising a burner, a cock controlling said burner and provided with a ratchet-wheel, a magnet, a sparking device, an armature operatively connected with said sparking device and provided with a pawl engaging said ratchetwheel, a shunt-circuit for cutting out said sparking device, a circuit-closing device for said shunt, including a movable arm, and a plurality of stops on said ratchet-wheel adapted to engage said movable arm, substantially as described.
